Answer:
   D.  8/2 +(-10)² = 104
Step-by-step explanation:
To find which statements are true, evaluate the expression for the given variable values. You do this by putting the numbers in place of the respective variables, then doing the arithmetic.
The respective expression values are ...
   A 83 ≠ 37 . . . . (4/2) +9² = 2 +81 = 83
   B 31 ≠ 61
   C 52 ≠ 61
   D 104 =104 . . . . true statement

I find it less tedious to write a function into a calculator or spreadsheet and let it do the repetitive math. Examples of the calculation are shown above.
 
        
             
        
        
        
In the first product the numerator of the fraction is greater than the denominator, therefore the fraction is greater than 1. On the other hand in the second product the numerator of the fraction is smaller than the denominator, therefore the fraction is smaller than one. That means the first product is greater than the second one.

Answer:
   5450
Step-by-step explanation:
Put 9% where r is in your formula and evaluate it. Of course, you must use the decimal equivalent.
   5000(1 +9%) = 5000(1.09) = 5450
The account will have 5450 in it at the end of the year.
 
        
             
        
        
        
So the first 10 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Since a prime number is only divisible by 1 and itself and greater than 1, our answers are 2, 3, 5, and 7. That's 4 numbers, or 4/10=0.4 of the 10. Since percentage is based out of 1, we can multiply 0.4 by 100 to get 40%. I hope that Helped :)
